Factual error: At the very end of the episode after Loomis is arrested, the camera pans away from the Detroit street, but mountains can be seen in the background on the horizon. There aren't any mountains or even large hills near Detroit.

A film reference to Star Trek: First Contact: Archer says something about a group of cybernetic creatures (The Borg), that tried to stop Cochrane from launching his mission into space that was stopped by a group of humanoids, that were also from the future (USS Enterprise NCC 1701-E).
